I agree that many ARE too lazy to bother either keeping track or spend the time negotiating... some are simply too busy. But, you see, this is my point, we are talking about time
If you don't have 30 minutes a year to negotiate your annual contract
Here you are talking about time
then you can afford whatever increase is applied
but here you are talking about money. While I am sure you would cite the age-old cliche that 'Time is money' the two are obviously not equivalent since a person with a lot of time on their hands is not by definition wealthy. And your defense of costs to business going up would carry more weight if they weren't making higher and higher profits each year. In many cases, their costs can be shown to be decreasing
(labor, taxes, etc.) They could get by just fine without raising rates, they do it anyway because they know it is a hassle for people to switch.
